Embodiment Construction

[0023] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1-Figure 3 As shown, a planar MRI gradient coil according to the present invention includes a gradient coil body 1 with a circular arc concave shape on one side as a whole, which breaks away from the shackles of the traditional cylindrical structure and reduces the impact of the gradient coil on the space in the magnet cavity. occupancy, so that the patient has a more relaxed examination environment, and the comfort is greatly improved. The gradient coil body 1 is installed on the examination bed 5. The gradient coil body 1 includes a main coil 2 and a shielding coil 3. The main coil 2 It is arranged diagonally to the shielding coil 3 to reduce eddy currents. There is a FOV space 4 in the middle to ensure the imaging area of ​...

Abstract

The present invention provides a planar MRI gradient coil, which includes a gradient coil body with a circular arc concave shape on one side as a whole, the gradient coil body is installed on an examination bed, and the gradient coil body includes a main coil and a shielding coil. The main coil and the shielding coil are arranged diagonally, and there is a FOV space in the middle. The beneficial effect of the present invention is to realize the shielding design, reduce the eddy current; Problem; Torsion optimization design was carried out to reduce noise and vibration.

Description

technical field [0001] The invention relates to the technical field of gradient coils in the technical field of MRI, in particular to a planar MRI gradient coil. Background technique [0002] The gradient coil is one of the core components of the MRI (Magnetic Resonance Imaging) system. Its main function is to convert electrical energy into magnetic energy and provide the encoding magnetic field required by the MRI system for scanning. At present, only a few companies in the world have mastered the gradient coil manufacturing technology. The gradient products on the market are divided into general-purpose and special-purpose. Among them, only the British Tesla company and Nanjing Cichen Medical Technology Co., Ltd. sell mature products for general-purpose coils. And special products need to be customized. [0003] With the development of the medical industry, many specialized hospitals have emerged, and their demand for dedicated MRI systems is increasingly urgent. Some med...
